Figure 7 is an end elevation looking at the lower end of the machine of Figure 1.

Figure 8 is a section on line VIITVIII of Figure 2. 1

Figure 9 is a section on line IX-IX of Figure 2. 2

Figure 10 is a tragmental sectional view showing certain details of construction.

The embodiment shown in the drawings comprises a casing formed 01 a top portionl and a bottom portion 2 which are held together in operative relation by bolts 3 and 1.

The lower part of casing 2 is formed with a depression 5 for reception of the energizing coil.

A plate or frame 6' as best shown in Figure 2, is inserted in one of the casing portions shown in the drawings as portion 2 and which plate rests on the bottom of said portion. Lateral projections 7 are provided for positioning the plate within the casing, while an end projection 8 positions the plate lengthwise in the casing 2.

An energizing coil 9 is secured to the plate 6 by means of its core 10 which is bolted at 11 to the plate. The core is a bipolar core having one pole 12 in the axis of the coil and the pole 13 disposed laterally of the coil and spaced a slight distance from the same.

The plate 6 has an upturned lug 14 which is curved in top plan view.

The armature 15 is attached by means of a bolt 16 to a spring 17 which is retained against the concave surface of the lug 14 by an adj usting screw 18, which screw has a reduced portion 19 threaded into the lug 1-52 and a shoulder 20 bearing against the opposite side of the spring 17 whereby the tension of the spring 17 may be varied with respect to the lug l4 tor adjusting the vibration of the armature 15.

A pole piece 21 is attached to the armature 15 iii-position to be influenced by the core 12 ot' the coil, while another pole piece 22 is attached to the armature in position to be influenced by the second pole 13. The second pole is provided for imparting greater pulling effect to the armature, thereby rendering the machine more efiicient in use.

The armature 15 has its tree end bent at an angle, with an end 23 projecting beyond the side of the casing 2. This end 23 serves a cuticle set or pusher.

Figure 3 shows the ends of the portions 1 and 2 of the casing as bein apertured or slotted, through which slot the cuticle pusher extends.

A plate 2 1 of non-magnetic meta is riveted at 25 to the bent portion 26 of the armature 15. Said plate is shaped as shown in Fig the operating tools.

ures 6 and 8. The upper portion of the plate 27 is inclined and is provided with two circular collars '28 and 29 which are threaded on the interior.

I A bufi er 30 is threaded into the collar 28 and a polisher 31 is threaded into collar 29 so as to be reciprocated or vibrated whenever the armature is vibrated by the coil.

An abrasive element-such as a file or sand board 32 is secured by means of projections 33 flatwise against the curved downwardly extending portion 34 of the plate 24, which file vibrates in the openingformed by the easing portions 1 and 2. A second file or sand board 35 is fastened by means of clips 36 against the plate 24 at right anglesto the file 32. which file 35 projects outwardly beyond the file 32.

The casing portion 2 is provided with a ridge 36. defining the lower margin of the aperture, which ridge serves as a linger nail guide, while the end of the casing 37 immediately underneath the guide 36 serves as a finger rest so that the finger may be turned about the rest 37 or the machine may be turned as a Whole about the finger when the same is against the rest 37 for governing the depth of cut by the file 32 and also governing the fineness of the cut.

A socket 38 is attached to the end of the plate 6 and projects through an opening Si in the casing at the opposite end thereto from This socket is arranged to receive a two prong electrical plug 40 for supplying an electrical current to the coil 9.

-The socket 38 is provided with three con tact conductor receptaclesA, B and G. A

A conductor 41 is connected to the cont actor A and to oneend of the coil winding. The conductor 42 is connected with a contactor B and to the other end of the coil winding at 43.

The two prong plug 40 being inserted in the socket 38 with the prongs in the contactors A and B and connected to a source ot alternating current, will energize the coil 9 for vibrating the arm 15, vibration being accomplished by reason ot the use of alternating current.

A make and break device D con'iprising an arm 44 and another arm 45 is secured to the plate 6 by insulating blocks 46 suitably lastened to the plate. The arm 44 carries a contactpoint 47 while the arm 45 carries a similar contactLS. Normally, these contacts are in engagement. I

A conductor 49 is connected to the contactor C of the socket 3S and a binding post 50 on the arm 44 0]": the make and break device.

.A conductor51is connected at one end to binding post 52 on the other arm 45 of the make and break device and at the other end of the coil and which carries an insulating projection 53 positioned over the pro ecting end of the arm l5 of the make and break device 1) to open the contacts 47 and 4-8 when lhc armature 15 is attracted towards the coil 5).

When direct current is available for operation of the machine, the two prong plug 40 will be inserted in the socket 538, with one prong in the contactor A and the other prong in the contactor C so that the flow of current will then be through the make and break device D and the coil 9 which is energizing the coil to attract the armature 15. 'hcn the arn'iature 15 has been attracted a. ccrlain distance, the insulated projection 53 will open the circuit through the contacts 47 and 43 on the two arms of the make and brcak dcvicc,

thus interrupting the flow of direct current to the coil 9 whereupon the flow of current ceases and the arm 45 springs back into position shown in Figure 2 whereupon the circuit through the contacts 47 and 43 is closed, again energizing the coil 9. This operation continues as long as the dlrccl' current 1s supplied to the machine, thus vibrating the armature 15 and its attached tools or manicuring devices.

The operation of the machine is as follows:

lVhen alternating current is used, the two prong plug 40 is inserted in the conlactors A and B of the socket 38 whereupon the coil 1) is energized to vibrate the armature .15. Such vibration reciprocates the bullcr 30, polishcr 31, cuticle set 23 and the files 32 and 35. The cuticle pusher 23 serves its purpose whcrcupon the nail is filed by bringing the machine against the end of the finger, with (he lingcr against the finger rest 37 and the nail extending over the guide 36 for filing by the lile 32 or 35.

Operation of the machine by direct current is the same except that the two prong plug 40 would be inserted in the conlactors A and C of the socket 38.

The plate (3 carries all of the instrumentalities above described and is secured in position within the casing portion 2 by means of the bolts 3 and -'l when the part I is applied over the part 2 and the bolts inscrlcd in place. Figure 4 shows a lower end of bolt 3 thrcaded at 54 for threaded engagement at 55 with the casing 2. The aperture in the casing 2 for the bolt 3 is formed by turning inwardlv the metal of the casing at the aperture for providing suliicient surface to receive the threads for the bolt.

The adjusting screw 18 may be turned in either direction to vary the vibratory movcmcnt of the armature 15 by inserting a screw driver in the slot 56 of said screw.

The device is very compact, a full sized device being no larger than the machine shown in Figure 1 and as a matter of fact as made it is smaller.
